Bug Description
https:/
Uses the built-in LVM snapshotting mechanism to create a new
snapshot, use qemu-img to extract the full root into an image file,
then delete the snapshot volume. Although we typically zero deleted
LVM volumes manually, this is not necessary for snapshots, as LVM
handles it for us (per the documentation).
